Non-apple partisans see their counterparts as brainwashed idiots incapable of thinking beyond what a single company offers in a sleek packaging; and those in favor of Apple see the critics as tasteless individuals with no sense of design, and who just don't get what it means to build hardware purely for the end user.
Sure there is. Determine the bias of people through empirical study. I've seen people "in love" with their iP*. Any claim against Apple they take as a personal insult, even when presented with fact after fact. It's annoying. In some way it's a bit like religion, really. Otoh I've seen anti-Apple people behave in the same way, hating Apple as it is the offspring of Great Old Ones and Satan. They might actually be only thing worst that Apple-lovers.
I doubt there's any way out of this :)
